UBE2A
UBE2A (Ubiquitin-conjugating enzyme E2 A) is a gene whose normal job is to hold cell growth in check. The public catalogues list it as a tumour suppressor, a biomarker and a DNA repair gene, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Diffuse large B-cell lymphoma.
Overview
E2 ubiquitin-conjugating enzyme that accepts ubiquitin from the ubiquitin-activating enzyme E1 and transfers it to a E3 ubiquitin-protein ligase. In vitro catalyses 'Lys-11', as well as 'Lys-48'-linked polyubiquitination. Together with the E3 enzyme BRE1 (RNF20 and/or RNF40), plays a role in transcription regulation by catalysing the monoubiquitination of histone H2B at 'Lys-120' to form H2BK120ub1.
CIViC holds 1 clinical evidence item and 0 assertions across 1 variant. IntOGen calls it a driver in 1 cohort (0 activating, 1 loss-of-function), covering Diffuse Large B-Cell Lymphoma, NOS.

- 3 · How drugs use it
No product in this corpus aims at UBE2A yet. Because the protein is lost rather than overactive, drugs either restore its function or exploit the weakness its loss leaves (synthetic lethality).

Biology
E2 ubiquitin-conjugating enzyme that accepts ubiquitin from the ubiquitin-activating enzyme E1 and transfers it to a E3 ubiquitin-protein ligase. In vitro catalyses 'Lys-11', as well as 'Lys-48'-linked polyubiquitination. Together with the E3 enzyme BRE1 (RNF20 and/or RNF40), plays a role in transcription regulation by catalysing the monoubiquitination of histone H2B at 'Lys-120' to form H2BK120ub1. H2BK120ub1 gives a specific tag for epigenetic transcriptional activation, elongation by RNA polymerase II, telomeric silencing, and is also a prerequisite for H3K4me and H3K79me formation. Involved in mitophagy by acting as a E2 ubiquitin-conjugating enzyme for PRKN. In association with the E3 enzyme UBR4, is involved in N-end rule-dependent protein degradation. Location: Late endosome; Lysosome (UniProt). Locus Xq24 (HGNC).

Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: IntOGen calls it a loss-of-function (LoF) driver in 1 cohort; CIViC holds 1 clinical evidence items on its variants; UniProt keyword "DNA repair". Evidence tier "clinical-evidence" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
